Well, let's cc Suren who actually wrote bc292ab00f6c ("mm: introduce vma->vm_flags wrapper functions").

These out-of-tree drivers should be converted to use the wrappers which bc292ab00f6c added. Their maintainers have a couple of months to do this before bc292ab00f6c is released in 6.3.
It's unfortunate. I guess it would be better if we were to find a way to permit these drivers to compile OK but to generate warnings, as an interim thing for six months or so. Perhaps there's some clever way.
